Analyze .NET code coverage

JetBrains dotCover is a .NET unit test runner and
code coverage tool that integrates with Visual
Studio and JetBrains Rider.

Make sure you know to what extent your code is
covered with unit tests. dotCover calculates and
reports statement-level code coverage in applications targeting
.NET Framework,
Silverlight or .NET Core.

Unit tests

Execute and debug unit tests and run coverage
analysis of unit tests in Visual Studio or using the
command-line utility. dotCover supports many unit
testing frameworks including MSTest, NUnit, xUnit,
and MSpec.

Manual test sessions

For manual test sessions, dotCover shows what parts
of code were called during the session and which
parts were not reached. Using the coverage analysis
data, you can easily get to the source code of the
tested application.

Detecting hot spots

Detect potential risk areas at a glance with Hot
Spots view, which shows the most complex methods with the
least coverage. Get your coverage analysis off to a
good start with an intuitive graphical
representation.

Seamless integration with Visual Studio
and JetBrains Rider

dotCover integrates with Visual Studio and JetBrains Rider, giving you
the advantage of analyzing and visualizing code
coverage without leaving the code editor. It
supports Visual Studio 2010 — 2017 and JetBrains Rider 2018.2 or later.

Continuous testing

dotCover can figure out on-the-fly which unit tests are affected by your latest code changes,
and automatically re-runs the affected tests for you.

The continuous testing mode can be switched on for any unit test session: this way
you can choose which tests you want to run continuously and which to run
the traditional way.

Benefits

Coverage highlighting

dotCover can visualize code coverage for your
convenience. You can see highlighted statements
covered and uncovered in a particular coverage session, right in Visual Studio.

Continuous coverage analysis

dotCover offers a console utility for use with a
Continuous Integration server. In addition, a free server-side version of dotCover is
built into TeamCity.
